bushing
Cylindrical bearing insert
A bushing is a cylindrical sleeve that reduces friction between moving parts or provides a snug fit for a shaft in a hole.
Bushings appear in machinery, plumbing, and electrical work—anywhere components need cushioning, alignment, or protection from wear.
In electrical contexts, a bushing insulates a conductor where it passes through a barrier: The transformer bushing cracked during the storm.
